MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 444,016, dated January6, 1891.

Application filed February 18, 1890. Serial No. 341,216- (No model.)

' To all whom it may concern.-

Be it known that I, TILLMAN PUETZ, Jr., of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inMechanical Movements, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to an improved movement which may be applied todifferent kinds and classes of machines; and my invention consists infeatures of novelty hereinafter fully described, and pointed out in theclaims.

Figure I is an end elevation illustrative of my invention. Fig. II is aside elevation of same, part in section.

Referring to the drawings, 1 represents a suitable frame, and 2represents a rack sliding on a support 3 and operated through means ofany suitable motive power. I have shown the rack operated by means of acylinder and piston 4, to which it is connected by the piston-rod 5; butother means for imparting a movement to the rack may be employed. Therack engages a cog-segment 6 and imparts movement thereto. The segmentis pivoted at 7, and is moved by the rack in the direction shown by thearrow, Fig. II, and back to the position shown in Fig. II, oscillatingor turning on its pivot 7.

8 9 represent two plungers of a brick-ma chine, a tobacco-press, orother apparatus. These plungers are connected by strips 10 tocross-heads 11, the strips passing through guides or ways 12.

13 represents platens or plates, against which the plungers press thematerial.

The segment 6 is connected to the crosshead 11 of the plunger 8 throughmeans of a pitman consisting, preferably, of short sleeves 14, pivoted,respectively, to the cross-head and segment and connected by a rod 15,which has a right and left thread and fits into tapped ends of thesleeves 14. The rod is provided with a non-circular portion 16 toreceive a wrench, by whichit may be turned to lengthen or shorten thepitman. The segment 6 is also connected to the cross-head 11 of theplunger 9 through means of a pivoted crank or link 17, connected by apitman 18 to the crosshead 11 and by a pitman 19 to the segment, thecrank or link having a wrist-pin 20, which passes through theadjacentends of the pitmen. The pitman 18 consists of short sleeves 21,connected, respectively, to the cross-head 11 and crank 17, and unitedby a rod 22, having a right and left thread and fitting in'the tappedends of the sleeves 21. This rod has a non-circular portion 23 toreceive a wrench, by which the rod can be turned to lengthen or shortenthe pitman. The pitman 19 consists of short sleeves 24, connected,respect ively, to the crank and segment, and which are united by a rod25, having a right and left thread entering the tapped ends of thesleeves, and which is provided with a noncircular portion 26, by whichthe rod may be turned to shorten or lengthen the pitman. The rods 15,22, and 25 may be provided with jam-nuts 27 to prevent their turningwhen adjusted.

The operation is as follows: The rack being moved in the direction ofthe arrow A, Fig. II, moves the segment 6 in the direction of the arrowB, which produces the upward movement of the plunger 8 and the downwardmovement of the plunger 9, the crank or link 17 moving in the directionof the arrow G. Then as the rack is moved in the reverse direction thesegment is swung back again, causing the plunger 8 to descend and theplunger 9 to ascend, and thus as the segment oscillates back and forththe plungers alter' nately rise and fall.

While I have described my invention as applied to a press havingplungers, it is evident that it can be applied to various purposes andobjects other than plungers, to be operated through the medium of themechanism I have described.

I claim as my invention- 1. The combination of a rack, a motor formoving the rack, a pivoted segment engaging the rack and moved thereby,objects to be moved, and adjustable pitmen connecting said segment tosaid objects, substantially as described.

2. In a mechanical movement, the combination of a pivoted segment, meansfor moving the segment,such as a rack, cylinder, and piston, anadjustable pitman connected to the segment and to an object to be moved,a sec- 1 left threads, a second pitman connecting the end adjustablepitman connected to the segsegment to a pivoted link or crank andconwent and to a pivoted crank or link, and a sisting of tapped sleevesand a rod having 15 third adjustable pitman connected to the right andleft threads, and a third pitman 5 crank or link and to an object to bemoved, connecting the crank or link to an object to substantially as setforth. be moved and consisting of tapped sleeves In a mechanicalmovement, the coinbiand a rod having right and left threads, subnationof a pivoted segment,a rack engaging stantially as set forth.
